3 Day Outlook
Sunday: The last of the rain will clear the north of the country soon after dawn and the morning should be generally dry and bright, with good sunshine in many areas. The day will become warm with temperatures rising to between 18 and 21 C., in southeasterly breezes. The best of the temperatures will be over Connacht. During the afternoon heavy thundery showers will break over Munster and Connacht but these will die away towards night. Winds wil be moderate southeast to easterly and with high humidities, there is also a risk that some sea mist and sea fog could drift onto parts of the south and east coast, thereby obscuring the sunshine.
Monday: It will be warmer and humid again on Monday with highest temperatures of 17 to 22 degrees - best in the Midwest and West. Further heavy thundery showers will occur across parts of south Munster and south Leinster, but most other places should be dry. Sea mist and sea fog will continue to be risk on exposed coastal regions.
Tuesday, Wednesday, Thursday: Staying warm and humid with hazy sunshine; a lot of dry weather but a continuing risk of thundery showers and local sea mist and fog. Highest temperatures of 16 to 21 degrees.
Weekend: Still warm but less risk of showers.
